What vitamin comes from the sun?

Vitamin D comes from the sun and is also referred to as ‘the sunshine vitamin’.Exposure to the sun is one of the most important and reliable natural sources of Vitamin D. 

Let us take a look at how you get Vitamin D from the sun.

How do you get Vitamin D from the sun?

Vitamin D is a very essential nutrient as it is required for a variety of different processes in the body. Getting Vitamin D from the sun is an unaffordable and convenient way as it only requires you to spend a short duration of time in the sun.

You can get all your daily Vitamin D requirements from the sun. As per the Vitamin D council, you can derive your Vitamin D daily value from the below:

Exposure to sunlight for 15 minutes if you are a light skinned person.

If you are dark skinned this might take a couple of hours

Not a lot of foods have sufficient amounts of Vitamin D, so you should always ensure that you make some time to be outdoors so that you can get some Vitamin D.

When your skin comes into contact with the sun’s Ultraviolet B (UVB) rays, the skin tissue cells usually commence the production of Vitamin D for use by the body. It should however be noted that a lot of exposure to Vitamin D can be cancerous.

Vitamin D also aids the body in the absorption of calcium which is an essential mineral for the growth and maintenance of healthy bones.

Vitamin D is required for the proper functioning of the nerves, muscles and immune system. A deficiency in Vitamin D can lead to soft bones and result in conditions such as rickets and osteomalacia. It can also lead to osteoporosis which is a condition which makes bones fragile and easy to break.

What are the factors that can prevent you from getting Vitamin D from the sun?

It is important to know that there are a variety of factors that can limit the amount of Vitamin D you get from the sun. For instance, wearing sunscreen lowers the body’s ability to produce Vitamin D. It should also be noted that sunscreen is important because exposing your skin for long periods without it can lead to development of cancer.

The body is also unable to make Vitamin D when it is exposed to sun rays coming through a window. This is because the glass usually blocks the sun’s UVB rays.

For some people they make less amounts of Vitamin D as compared to others. Others may be not able to release adequate amounts of Vitamin D into their blood circulation from the fat cells.

There are others who cannot completely activate VitamiN D in their bodies to a state that can be used by their bodies. Such people are at risk of suffering from Vitamin D deficiencies and they include the below:

  • The elderly
  • Dark skinned people
  • Obese people
  • People who suffer from kidney or liver disease.

What are the dangers of too much sunlight?

Well it’s said that too much of something is poisonous. The same applies to sunlight as too much of it can be potentially dangerous.

Let us take a look at some of the risks of too much sunlight:


Too much exposure to the sun can result in sunburn which has symptoms such as redness, pain, swelling, blisters and tenderness of the skin.

Eye damage

If you are exposed to UV light for long you can also damage your retina. This can increase the risk of development of eye cataracts

Aging of the skin

You can develop skin that is wrinkled, loose or leathery as a result of spending too long in the sun. Too much exposure to the sun accelerates aging skin.

Skin cancer

Being exposed to too much UV light is a risk factor for skin cancer.

Heat stroke

It is also referred to as sunstroke and this is when the body’s core temperature goes beyond due to a lot of sun or heat exposure.

If you plan on spending a lot of time in the sun, always ensure that you wear sunscreen to avoid being sunburned. Make sure that you apply sunscreen every 2 to 3 hours you spend in the sun.
